Observational Study
Construct validity of Movement-Evoked pain operational definitions in older adults with chronic low back pain.
Movement-evoked pain (MeP) may predispose the geriatric chronic low back pain (LBP) population to health decline. As there are differing operational definitions for MeP, the question remains as to whether these different definitions have similar associations with health outcomes in older adults with chronic LBP. ⋯ Aggregate posttest MeP was linked to poorer health outcomes in older adults with chronic LBP, but MeP change scores were not. Future studies should consider that the construct validity of MeP paradigms partially depends on the chosen operational definition.

The purpose of this study was (1) to examine the degree to which perceived burdensomeness mediates the relationship between pain severity and suicidal cognitions and (2) to determine whether this mediated relationship was moderated by pain acceptance. We predicted that high levels of pain acceptance would buffer relationships on both paths of the indirect effect. ⋯ Higher acceptance mitigated the relationship between pain severity and perceived burdensomeness and the relationship between perceived burdensomeness and suicidal cognitions in this clinical sample of patients experiencing chronic pain. Findings indicate that any improvement in pain acceptance can be beneficial, and they provide clinicians with a clinical cut-point that might indicate lower vs higher suicide risk.
